CAR-COUPLING.

such as will enable others skilledin the art to which it appertains tomake and use the same.

My invention relates to that class of carcouplers which are providedwith a pinsupporting catch, which releases the pin and permits it tofall when the link enters the draw head.

The object of my invention is to provide a .catch that willautomatically return to its place whenthe link and pin are withdrawn Thenature of my invention consists of constructions and combinations, allas will hereinafter be described and claimed, reference being had to theaccompanying drawings, in Which I Figure 1 represents a longitudinalsection through two draw-heads, one having thelink secured therein andthe other ready to receive the link; ig. 2, a detail showing thependulum. l

A A represent the draw-heads, B the link, and C G the pins. Thedraw-heads are each provided with an upperand lower pin-hole, a a,similar to those in use, anda bolt-hole, a, back of the upper pin-hole.This hole a may be vertical or oblique, and round, square,

or any other form in cross s'ection. Through this opening is inserted abolt, D, screw-- threaded at itsupper end, d, and to its lower end ispivoted in any suitable manner a swinging orpendulum catch, E. As shownin the drawings, the catch is attached to the bolt by means of a pintle,e.

The pendulum E may be of any desired form, and should be provided with acatch, 6', and weighted at its lower end, 6 This end should be-weightedsufficiently to support the pin in the hole a preparatory to its fallthrough the lower hole, a, to catch the link, which, when it strikes thependulum E, forces the latter back and frees the'catch c from the pin.

, In the draw-head A the link is shown held therein by the pin. Theweighted part of the pendulum rests against the upper side of the link,which is thereby held in such a position that it can readily pass intothe draw-head A and release the pin, which will lock the coupling. Ifdesired, the draw-heads may be recessed at a, so that the pendulum mayhave greater swing when the link is pushed into the draw-head.

The preferable mode of placing the pendulum in place is to attach it tothe bolt and pass the latter upwardly through the opening a and holditin place by means of the nut F, which is screwed upon the end d; orthe bolt may be passed through the hole a and the pendulum attachedthereto within the drawhead.

It is obvious that this device may be attached to any of the draw-headsnow in use by simply drilling the hole a in the upper part thereof.

' What I claim as new is- V 1. In a car-coupler, the combination of ahead having pin-holes and a bolt-hole, a pin, and a catch suspended fromsaid draw-head by a bolt passing through the bolt-hole in the ISAAC H.TRABUE.
